Sigma Profil with reluctance motor

Responsible use of resources is one of the key factors to which Kaeser Kompressoren owes its success. As a leading compressed air systems provider and a renowned industry trendsetter, Kaeser is proud to present yet another technological milestone at Hannover Messe 2017. For the first time, the ASD series of variable-speed compressors will be equipped with synchronous reluctance motors – a major advantage due to their considerably lower losses in the crucial partial-load range, compared to asynchronous motors.

 

With Sigma Profil and innovative drive concepts, Kaeser’s ASD series of rotary screw compressors offer flow rates ranging from 3.15 to 5.5 m³/min, delivering outstanding performance and reliability, combined with energy efficiency and space-saving design.

 

The trendsetting company is now taking yet another important step, to be presented to the wider public for the first time at Hannover Messe 2017 – further consolidating its reputation as a premium provider. Kaeser is now releasing its ASD series of variable-speed rotary screw compressors with a completely new drive technology. The major advantage of this complete solution, which was developed in close partnership with Siemens,  is that it delivers efficiency gains of up to ten per cent in the partial-load range. This drive principle has been understood for decades. But only now has its implementation in production series motors attained the technical perfection required to benefit users throughout the world.

 

Variable-speed drive with high system efficiency

With our variable-speed versions (SFC) of the ASD series, we offer customers worldwide an opportunity to embark on a path of minimal energy consumption – and minimal operating costs. This is important because compressed air stations are often constructed on a modular basis: Continuously running compressor systems with IE3 and IE4 motors cover base load demand, whilst additional peak-load compressors respond flexibly to meet extra demand; the system as a whole is controlled and co-ordinated by a SIGMA AIR MANAGER 4.0 master controller to ensure maximum efficiency.
